1 HHHHIH lllllllllll g R RICHARD gamma TaaZZ wiwm z'tmay concern:- l I Be it known that we, ERNEASTYQRICI-IVARD PELLrNe,-a subject of the ,King of Great Britain 'and 'lreland, residing. at the Engineers Hous selsdon Park, Croydon, in the county of Surrey, England, and VIo'ron ALEXANDERh IATTIOK, a'subject of the King of Great Britain and Ireland, residing at 83 StJJames Avenue, 'Beckenham, inithe county of Kent, England, have invented a new and useful Improvement in Motor Tractors, for which we have obtained a patent in reat Britain, October 31, 1919, Patent No. 149,153,) of which the following is a full and complete specification.

'This invention relates to motor "tractors and has for its object a construction which is specially adapted for the haulage of plows of the one-way type and which can be readily converted into a tractor suitable for general haulage purposes.

WVe attain this end by the construction hereinafter more particularly specified and shown in the accompanying drawings in which 7 Figs. 1 and 2 are views in side elevation and plan respectively showing the tractor arranged for hauling acne-way plow, and

Figs. 3 and 4'are similar views showing the tractor converted foruse for general haulage purposes. 7 I V v a Throughout the views similar parts are marked with like letters of reference.

The tractor comprises essentially a central 7 or main frame having a transverse axle carrying two driving wheels, the power unit, the variable speed and reverse gearing and the transmission gear all of which may be a of any suitable type, and as they form no part per se of the present invention call for no furtherrdescription.

On one side of the main frame a at one end thereof is permanently attached an extension arm 6, and on the same side of said main frame at the opposite end thereof is detachably attached by means of fish plates :0 or the like another extension arm 0. On each of these extension arms preferably on the inner sidesthereof aresteering heads 6? adapted to carry the forks dcarrying the steering wheels 6 and e. Said extension arms are braced to the main frame by diagonally arranged stay bars f which are'secured to said extension arms and tosaid main frames by meansof fish plates w or .steeringfwheel e -to the same-end of the a means of bolts'or the like.

any other suitable rigid and detachable couplings. 1 is When it is desired to convert the tractor as arranged for plowin'gto atractor for gen eral haulage purposes the stayjbars f are firstremoved, theidetachable extension arm 01 is then removed from themain frame and is fixed to the same end ofsaid main frame asthe'exten'sion arm 32 so. as tohbringthe mainframe as, the. steering wheel? '6. andsaid two extension arms are braced together by meansof a suitably shaped cross member 71 which is fixed to said extension arms by The. steering arm 0 is coupled to the steering wheel e car ried by the permanently fixed. extension arm b by means of arms m and m and a coupling link m so that the motion imparted to the permanently located steer-- ing wheel e is also communicatedto .the steering wheel e.

Whatowe claim is: l a

1.A motor tractor comprising a main frame supported by two drivingrwheels, and,

adapted to carry the power unit and the. i 7

transmission gear from said power unit to} 7 said wheels, two beams extending from-thea a same side thereof one of said beams being; l

opposite ends of the main frame on the apermanent fixture to said fr'ame'andtheother 'being detachable from said frame and, i I

capable of attachment to eitherend thereof,

a-steering wheel carried byeach of said beams and means ,for' coupling the two beams together at one end of the main fram 1;

2. A motor tractor comprislng a main frame supported bytwo driving wheels'and l .adaptedto carry the power unit and the transmission gear from said power unit to said'wheels, two beams extendingifrom' the opposite ends of the main frame on the same side. thereof one of said beams'being permanently fixed to said frame and the other of said beams being detachably attached to said frame. and adapted to be attached to either end thereof, a steering wheel carried by each. of said beams, detachable stay bars'attached to said beamsnear their free ends and at-. tached' tothemain frame on the opposite sides thereof and means for coupling the two beams together at one end of the main j frame. V r 7 motor tractor comprising a main frame supported by two driving wheels, two extension beams one at each end of the main frame and both on one side thereof one of said beams being permanently fixed to said frame and the other detachably mounted on said frame and capable of being shiftedand fixed to the other end of the main frame so as to be parallel with the fixed beam, a head or socket carried by each of said beams, a fork mounted in each head or socket, a steering wheel mounted in each said fork, stay bars operating between the beams and the main frame, means for securing the free ends of the two beams to one another, coupling mechanism'between the two steering wheels, and controlling mechanism for operating said steering wheels through said coupling means.

4;. A motor tractor comprising a main frame supported by two driving wheels, two

extension beams one at each end of the main frame and both on one side thereof one of said beams being integral with the main *frame and the other of saidbeams being detachable from said main frame and adapt head or socket mounted on the inner side of each of said beams, a'fork mounted in each head or socket, a steering wheel mounted in each said fork, a cushioning spring located between the top of each said forks and the underside of each ofsaid heads or sockets, stay bars detachably attached to the free ends of said beams and to the mainframe, means for coupling the free ends of the two beams together when they are located at the same end of the main frame, coupling mechanism between the two steering wheels, and

controlling mechanism for operating said steering wheels throughgsaid coupling means.
